Keep high-voltage spark reaching every plug in the right order with the Standard Ignition Distributor Rotor FD-15. It is a direct-fit replacement for the listed applications: the 1928-1931 Ford Model A, the 1928-1931 Ford Model AA and the 1932 Ford Model B. The rotor turns with the distributor shaft and passes the coil's voltage to each cap terminal in firing order.
Standard's distributor caps and rotors draw on decades of research and development.
Signs this part may need replacing: The rotor may need replacing if you notice misfires, hard starting or a no-start, rough running, or a rotor tip that looks burned, worn, cracked or carbon-tracked. These symptoms can have other causes, so diagnose the ignition system first. If a worn rotor is the cause, the FD-15 replaces it. See the Buyer's Guide tab for complete application details.

This part cross-references / interchanges with the following part numbers:
What vehicles does the Standard FD-15 distributor rotor fit?
It is listed for the 1928-1931 Ford Model A, 1928-1931 Ford Model AA and 1932 Ford Model B. See the Buyer's Guide tab for complete application details.
What does a distributor rotor do?
It turns with the distributor shaft and carries high voltage from the cap's center terminal to each outer terminal in firing order, sending spark on to the plugs.
Why does this rotor use brass segments?
Standard uses solid brass segments on its distributor rotors for better conductivity and a higher-voltage spark to the plugs.
What does the alkyd material do?
The high-grade dielectric strength alkyd resists dirt sticking to the rotor. That decreases carbon tracking and helps extend service life.
What are signs a distributor rotor may need replacing?
Misfires, hard starting, rough running, or a burned, cracked or carbon-tracked rotor can be signs. Other parts can cause the same symptoms, so diagnose the ignition system first.
